The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This tutorial demonstrates how to create domains for modeling inside and outside of an imported CAD assembly. You will also learn how to use the defeaturing tools for deleting details from the imported geometry. Read More
The model has its emphasis on heat transport in a very small heat exchanger that is commonly used in the field of microelectromechanical systems (MEMS). In this case, it might be a reactive processes that needs heating. The heat exchanger itself is constructed by stacking several ... Read More
When designing oxygen masks for delivering respiratory support to patients via BiPAP and CPAP, multiphysics modeling helps visualize the flow pattern inside the mask for a given design. From there, it is possible to estimate oxygen consumption, carbon dioxide accumulation, and ... Read More
The model illustrate the technique to calculate the magnetic stiffness in a 3D geometry of a permanent magnet axial magnetic bearing. The Magnetic Fields physics is used to model the bearing and compute the magnetic forces. The Deformed Geometry and Sensitivity physics are used to ... Read More
Modeling the penetration of a needle into soft materials, such as gelatin, involves several complex mechanical challenges, including large deformations, high friction, contact forces, and material failure. This example simulates the needle insertion process into tissue-like materials ... Read More
This is a small 2D demonstration model that couples the Linearized Navier-Stokes, Frequency Domain, Solid Mechanics, and Turbulent Flow (k-epsilon) physics interfaces to model the vibrations of a plate located in a 2D viscous parallel plate flow. This type of model is used to model fluid ... Read More
A ribbon mixer (sometimes referred to as a ribbon blender) is a mechanical device that is commonly used to mix different types of granular material. Ribbon mixers are widely used across various industries including food processing, pharmaceuticals, chemical industries, agriculture, ... Read More
Light collimation or focusing is a basic task often needed when working with lasers in the lab where singlets are used due to their simplicity. If a plano-convex lens is used for the task, there is a correct lens orientation that minimizes aberrations. A useful rule-of-thumb is to ... Read More
In this tutorial, an uncertainty quantification analysis is performed on the Microstrip Patch Antenna model from the RF Module Application Library to explore how variations in input parameters, such as material properties or geometric variations, impact the antenna’s performance in terms ...
